SRU::Response::Scan is a class for representing SRU scan response A scan request allows SRU clients to browse the indexes of an SRU server,
much like you would scan the back of a book index to look up particular terms in the body of the book.
The scan response bundles up the terms that were looked up.

Get/set the terms associated with the response. Be carefult you must pass in an array ref of SRU::Response::Term objects, or expect an array ref back when getting the values. If you don't bad things will happen.
